Subject: [PATCH v3 0/4] Fixes for setting event freq/periods
Date: Fri, 11 Sep 2020 19:56:51 -0700	[thread overview]
Message-ID: <20200912025655.1337192-1-irogers@google.com> (raw)

Some fixes that address issues for regular and pfm4 events with 2
additional perf_event_attr tests. Various authors, David Sharp isn't
currently at Google.

v3. moved a loop into a helper following Adrian Hunter's suggestion. 
v2. corrects the commit message following Athira Rajeev's suggestion.

David Sharp (1):
  perf record: Set PERF_RECORD_PERIOD if attr->freq is set.

Ian Rogers (2):
  perf record: Don't clear event's period if set by a term
  perf test: Leader sampling shouldn't clear sample period

Stephane Eranian (1):
  perf record: Prevent override of attr->sample_period for libpfm4
    events
